如何在区块链中实现 ZK 证明系统呢？目前大致有两种方法实现电路 - 基于电路的系统 (circuit based) 以及基于虚拟机的系统 (vm-based)。 首先，基于电路的系统的功能是将程序 (program) 直接转化为约束条件 (constraints) 并送入证明系统 (proving system)；基于虚拟机的系统通过指令集 (ISA) 执行程序，在此过程中产生执行轨迹 (execution trace)。这个执行轨迹之后会被映射成约束条件，然后被送入证明系统。 对于一个基于电路的系统，程序的计算由执行程序的每台机器 (machine) 进行约束。而对于基于虚拟机的系统，ISA 被嵌入到电路产生器 (circuit generator) 中，并产生程序的约束 (constraints)，同时电路产生器有指令集、运行周期、内存等等限制。虚拟机提供了通用性，即任何机器都可以运行一个程序，只要该程序的运行条件在上述限制范围内。 欢迎交流zk电路设计

Proof of identity product review
Amazon, Nike, yelp, Starbucks, etc. all web2 platforms have a product review section for users to detail what they like, dislike, and provide rating. However, new buyers have to trust that these high reviews are given by actual buyers and real people. This can be solved in web3 by: 1. ZK identity proofing 2. Token gated product reviews

Adding fruitchain to an appchain
When an appchain's main use case grows big, the original consensus protocol might not be decentralized and secured enough. As a result, some of the fastest-growing appchains might seek to upgrade their consensus protocol in the near future. If an appchain does not want to switch to a full Nakamoto consensus due to cost considerations, it might well consider switching to a hybrid consensus, and probably adding some cool features like Fruitchain. https://eprint.iacr.org/2016/916.pdf
Blockchain with respect to hydrology
This project leverages on the potential use of Blockchain technology to accurately predict the level of water and weather based on the data available.
No Profile NFT Minting Page
First, let me introduce myself as Kakte. Since 2017, I have focused on community management in Indonesia. Recently, I have been thinking about taking part in the Builder ecosystem. And Here is #MyFirstIdea Create a collectible NFT running on top of the Venom Testnet. NFT Name: No Profile Network: Venom Testnet Concern: Standing equally, working together. Unique Points: 1: People can upload photos with a 1:1 ratio, and then the system will generate the image into a silhouette with the same background and primary color. 3. People can mint the results. Challenge: Wallet integration connects to Venom Integration of the NFT collection into Venom Upload and generate image features, etc. I can't work alone; I need someone to build this product together, and so far, I have.

Can we onboard unions to the blockchain?
We want to help bring back the idea of a "card-carrying member of a union," by creating a protocol that allows labour unions to issue signable membership cards through a simple interface. We're looking to explore how Blockchain technology and principles can be used as a tool to help make traditional community-owned organizations like unions more democratic, transparent and decentralized. Looking to build solutions leveraging: - Account abstraction - Governance protocols - Social verification and recovery - Decentralized social Since 1981, the number of unionized workers in Canada across Canada declined by 11%. While over 4 Million workers continue to be members of various unions across Canada, many of these organizations struggle to modernize their governance and membership engagement processes, leading to a decline in member participation and apathy. While these tools exist for DAOs, none have been developed with traditional unions in mind. We believe this presents a great opportunity to to bridge that gap.
Electrostatic traveling wave for Mineral processing in Space
#MyFirstIdea For any SRU process on the Moon, Mars or any other body, the material flow comprises three key stages; excavation, beneficiation and extraction. Traditional terrestrial way of minerail processing does not work in Space. We are trying to use electric methods to do the beneficiation processs. Electrostatic traveling wave (ETW) is a technology that can manipulate and control particle motion due to the action of Coulomb force, dielectrophoretic force and other forces related to their physical properties. ETW systems are particularly well-suited to the space environment due to the lack of moving parts and absence of moisture.

Decentralized Community-Supported Agriculture
Help me revive this project idea I came up with way back in 2015! Link to old whitepaper: https://docs.google.com/document/d/1jntZtiw0VQQ6ZctVyWsCcg-ZGvv6MCSvlFIIPG5GDSg/edit?usp=sharing "This document outlines a proposal for an agricultural blockchain service which aims to rebuild the broken food system, starting at the community level, by adapting an existing business model (CSA) and leveraging the Ethereum network’s potential for distributed governance, platform cooperativism, and planetary-scale computation." "FarmShare differs from both original and contemporary community-supported agriculture in several key ways. Rather than operating as a single farm, FarmShare serves as a platform for entire communities to create a parallel economy for the production, processing, distribution, and consumption of local food. Furthermore, shares need not be purchased ahead of time at a flat fee, but may also be earned by supporting and contributing to the local food system. Shares may be issued for volunteering on the farm, transporting food, contributing to a crowdfunding campaign, sharing processing equipment, participating in an educational workshop, and anything else a community assigns value to. Shares may be exchanged for food from a network of farmers markets, co-op stores, specialty markets, restaurants and food pantries."
